I think we all know the struggles of finding area bosses to get olaf done. Nx farmers clear out all bosses and since they do so at the same time, respawn timers are synced up and you know nothing is going to spawn for at least a few hours. I think area boss farming is a great way for new players to get nx, but I think there should be some limit to it. I think people should be limited to killing like 10 or so area bosses for nx. How this can be implemented: Have a daily quest that, once active, allows you to hunt for quest nx tokens from area bosses. Once you've hit the limit for tokens, you can submit the quest to get the payout. Higher levels unlocks new nx limits. 3000 nx until level 70 5000 nx until level 120 7000 nx for lvl 120+ This would only apply to area bosses that spawn randomly. Pap/chao/eph/expedition bosses give nx directly just as they do currently. This system wouldn't be foolproof, you can always create new characters to get by it. But I think it will be enough of a deterrent to get people to farm other stuff instead of camping Timer 24/7.
I did olaf a lot of times, usually its pretty easy to find the bosses, from time to time you need to go and try later. The only really hard one is blue mushmom but the issue is the 24h timer and not nx farmers.
